We have developed custom web part (Sandbox solution) for SharePoint Online. We were facing an issue in it. To fix that issue we got a solution as below :
1. Add 'ReceiverAssembly' attribute in manifest root node for WSP.
2. Add 'ReceiverClass' attribute in manifest root node for WSP
We have no idea how to add above to WSP.
Any help on how Receiver Assembly and Receiver Class attribute can be set to WSP menifest-
Thanks Ranveer Katiyar
